Hi I have to replace the inlet water valve on my sub zero 532, when I took off the black trim plate I saw the valve on the lower left front side, NOW there is a black bar going accross the front and the valve is behind it, HOW DO I GET TO VALVE ? Barry

I think that is the problem, my wife filled the ice maker and it made ice, so i figured it was the inlet valve, I replaced that and still no ice,,,so my next question is how do i fix the frozen fill line and where is it

it's in the back of the icemaker, should see a plastic tube that fills the tray. If it is frozen you could either put a hair dryer to it or pull it out from the back of the unit (if you have access to the back) and run warm water through it.
